Potomac Highlands was historically an old farm property that had become mostly forested over the years and the property contained significantly steep slopes rising up over 80’ directly from Seven Locks Road to the rear of the property. The adjacent properties to the north and south of the property are fully developed townhouse communities and the pristine forested area of Cabin John Park is adjacent to the east. The dramatic grade changes on-site created significant site access challenges and protection of the surrounding communities and important adjacent environmental features would be required.
GLW provided full entitlement processing services from concept planning, preliminary plan through site plan approval; landscape architecture/design; and full engineering services including subdivision platting, site grading, utility design, public road improvement design, ADA access, forest conservation, sediment control and stormwater management (SWM) design/approval.
GLW analyzed the complex site conditions and developed a creative access entry road pattern and interdependent multi-level retaining wall system to provide safe vehicular and pedestrian access to the site from Seven Locks Road, at the same time creating a dramatic site entry feature for the project. The use of curved retaining walls in combination with decorative native stone provided an appealing and welcoming entry that maximized the site’s elevation as a effective selling point for the views and prominence of the townhouse units at the site. GLW engineers designed state of the art ESD (Environmental Site Design) stormwater management through the use of creative mico-bioretention to provide maximum stormwater management treatment and protect the sensitive downstream watershed.
